My fathers's dear friend Stese was close with the old brewmaster at Anchor Steam. He was in his 90's at the time and one day he told Stese to start following him around the brewery and watch how he did things so he could take over for him when he was gone. Stese dutifully observed the brewmaster and took over his duties when he died. Soon there was a kid following him around taking notes on a clipboard. Fritz Maytag took over the operation, expanded it, bought a fleet of trucks and gave steam beer in SF a second life.
